CAR-TRUCK.

Specification of Letters Patent.

Patented May 8, 1912?.

Application filed August 21, 1915. Serial No. 46,723.

To all whom it may concern:

Be it known that I, GEORGE E. MARBLE, a citizen of the United States, residing at Dubuque in the county of Dubuque and State of Iowa, have invented certain new and useful Improvements in Car-Trucks, of which the following is a specification.

In the repair of railway cars and other cars, there has been difficulty experienced in removing the journal box and axle with wheel, on account of the height the end of the truck must be jacked up in order to get them in position to be removed. There is also considerable expense connected with these different modes of construction.

The object of my invention is to overcome these difficulties and to provide means whereby the journal box with axle therein may be securely held in the frame of the truck of the car and still to enable it to be removed without raising the truck, farther than sufficient to relieve the journal box from the weight of the car and, further to appreciably reduce the cost of construction.

I will point out in the following specification the manner in which I accomplish the foregoing objects and others, and the mode of operation and will illustrate it in the accompanying drawings which form apart hereof.

Figure 1 is a side elevation of a frame having my device attached in one end.

Fig. 2 is a side view of my device separated. Fig. 3 is a detail of the end of the frame broken away to show the mortise.

F ig. 4: is a plan view of the end of the frame showing the opening and mortise.

Like characters of reference denote corresponding parts in each of the drawings.

In the practice of my invention, I construct an ordinary body 2 of a frame of the truck, the ends of which I form into my device. Integral with the body is cast an arm 4 that is slightly bent at its lower end at 5 sufficient to conform to the bottom of the journal box. The top 6 of the frame is extended out the length of the width of the top of the journal box and upon the top of the frame over the journal box is a lug 8 provided with an opening 9 therethrough.

The end 6 of the frame including the lug 8 has a rectangular, vertical opening 10 therethrough and is recessed or mortised at 11 on both sides of the opening 10, in which opening and recess is removably secured a member 15. The member consists of a plate 16 with a lug 18 on top of the plate which is provided with an opening 20 adapted to register with the opening 9 in the divided lug 8 and through which and the opening 10 a safety pin or bolt 17 passes, to hold the member in place in the mortise and recess in the end of the frame.

The plate is also provided with a lug 2:2 adapted to fit in the rectangular opening 10 in the under side of the end of the frame. The outer end of the member 15 is provided with an arm 25 that is set at right angles to the plate 16 and extends downward along the side of the journal box to near its base.

The manner of assembling and operating this device is substantially as follows:

The end of the frame of the truck is placed against the journal box 30 with the arm against the side of the journal box and the bent point 6 of the arm beneath the journal box as shown in Figs. 1 and 2. Then the member 15 is placed in the recess 11 with the lug 18 between the lugs 10 and pressed down until the lug 22 enters the base of the opening in the frame and the opening 20 registers with the opening 10 in the lugs 8 and the arm 25 projects down the side of the journal box 30 and a safety pin or bolt 17 passes through the openings 20 and 9 and firmly fixes the member 15 in the recess and the opening of the frame. In this manner the journal box is rigidly held in the grasp of the member and the bent arm of the end of the frame.

When it is desired to remove the journal box the safety pin is withdrawn from the openings 9 and 20 and the member 15 with drawn from the recess. And then the frame of the truck is lifted simply enough to relieve the pressure of the frame upon the journal box and the journal box and wheel are readily drawn out.

It will be seen by this mode of construction that it is not necessary to jack up the car wheel, journal box and frame but only to raise the frame so that it will relieve the pressure upon the top of the journal box without raising the wheel or thejournal box.

It will also be seen that the cost will be very slight in fitting the end of the frame as the member 15 may be cast and also the frame with the bent arm 4.

Having now described my invention what I claim is 1. In a device of the character described, a frame, provided with a recess in its outer end, a journal box, an arm integral with the frame near its end and said arm bent at its lower end under the journal box, a member, and means for removably securing said member inthe recess in the frame and engaging one side of the journal box, said arm and member being entirely disconnected from each other at their free ends.

2. In a car truck, a side frame provided in its end with a pair of spaced arms between which the journal box is adapted to fit and be held against vertical displacement, and a removable member on one of said arms and free from the other arm and adapted to hold the journal box from horizontal displacement, the arm to which the removable member is fitted being provided With a recess, and the removable member having a lug adapted to fit in said recess to prevent horizontal displacement of the said removable member.

3. In a device of the character described, a journal box, a frame provided with a recess in its outer end, a lug on opposite sides of the recess and said end resting on the top of the journal box, an arm connected to the frame at substantially right angles to the frame and bent at its lower end and engaging one side and a part of the base of the journal box, a member provided with a lug and adapted to rest in the recess in the end of the frame with its lug between the lugs on the frame, and means including a safety bolt for securing the member in the recess in the frame.

In testimony whereof I affix my signature in presence of two witnesses.
